Description
[0001] TITLE OF THE INVENTION: AN APPARATUS FOR VENTILATING AN ENVIRONMENT
[0002] FIELD OF THE INVENTION
[0003] The present disclosure is generally related to ventilating an environment. Particularly, the present disclosure is related to an apparatus, in respect of ventilating an environment (an apparatus, for ventilating an environment). More particularly, the present disclosure is related to an apparatus, in respect of ventilating an environment, which dynamically addresses comfort needs of occupants directly.
[0004] BACKGROUND OF THE INVENTION
[0005] Centralised air conditioning systems (or apparatuses), with ventilation provisions, are known in the art. However, such apparatuses / systems are: of a complex configuration; expensive; and predominantly cater to requirements of large commercial buildings, where fresh air integration is followed, due to mandate or to meet green building requirements.
[0006] Further, at certain times, such apparatuses / systems may not provide ventilation at all, resulting in compromised indoor air quality. Furthermore, when such apparatuses / systems are employed, ventilation rates are predetermined, and remain constant, throughout the day, regardless of actual indoor air quality. This approach may result in over-ventilation, during periods of low occupancy, or when the indoor air quality is already within acceptable limits, resulting in high energy consumption.
[0007] In addition, there exists significant disparities, in the availability of similar apparatuses, for standalone facilities that span categories, including, but not limited to: multi-dwelling units; individual homes; small to medium offices; showrooms; banks; spas; salons; supermarkets; ATMs; restaurants; gyms; clinics; dispensaries; auditoriums; and / or the like.
[0008] There is, therefore, a need in the art, for: an apparatus, in respect of ventilating an environment, which dynamically addresses comfort needs of occupants directly, which overcomes the aforementioned drawbacks and shortcomings. SUMMARY OF THE INVENTION
[0009] An apparatus, for ventilating an environment, is disclosed. Said apparatus broadly comprises: a controlling unit; a fresh air supply fan; a fan coil; and a reservoir system.
[0010] Said controlling unit broadly comprises: an at least a carbon dioxide sensor or oxygen sensor; a sampling fan; an at least a temperature sensor; an at least a humidity sensor; an at least an infrared sensor; and a controlling member.
[0011] Said controlling unit may also comprise: an at least an indoor air quality sensor; and an at least a volatile organic compounds sensor.
[0012] Said at least one carbon dioxide sensor or oxygen sensor senses carbon dioxide levels or oxygen levels of an environment, where said apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to a controlling member.
[0013] Said sampling fan draws in surrounding air, and directs it, towards said at least one carbon dioxide sensor or oxygen sensor. Once said air is sampled, said sampling fan also exhausts said air, ensuring a constant flow of fresh samples.
[0014] Said at least one temperature sensor senses a temperature of said environment, where said apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to said controlling member.
[0015] Said at least one humidity sensor senses a humidity of said environment, where said apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to said controlling member.
[0016] Said at least one indoor air quality sensor senses indoor air quality levels of said environment, where said apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to said controlling member.
[0017] Said at least one volatile organic compounds sensor senses volatile organic compounds levels of said environment, where said apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to said controlling member. Said controlling member is communicatively associated with: said at least one carbon dioxide sensor or oxygen sensor; said at least one temperature sensor; said at least one humidity sensor; and said at least one infrared sensor. Said controlling member is configured to monitor and control operations of said apparatus, by comparing said sensed data, with an at least a threshold value or an at least a threshold range (or respective threshold values, or respective threshold ranges).
[0018] Said controlling member is communicatively associated with an air conditioner and a ceiling fan, or said controlling member is communicatively associated with only said air conditioner, through said at least one infrared sensor.
[0019] Said fresh air supply fan broadly comprises: a filtration member; and a honeycomb filter. Said filtration member captures dust particles, pollen, mould spores, allergens, and other impurities, which are present, in incoming fresh air. Said filtration member is replaceable or washable.
[0020] AC condensate water or tap water passes through said honeycomb filter, upon said controlling member determining that said sensed humidity is between a predefined threshold value and a second predefined threshold value. Said condensate water or tap water passes through said fan coil, upon said controlling member determining that said sensed humidity is above said second predefined threshold value.
[0021] Said reservoir system broadly comprises: a collection tank; a tank that houses a cooling tower; and a third tank that houses a compressor chiller and its (compressor chiller’s) copper coil.
[0022] Initially, said condensate water is collected, in said collection tank; it is then directed, to said tank. Within said tank, said condensate water undergoes a process of additional cooling, through induced evaporation. Said tank comprises an aerator. Said tank also comprises an additional pump, for spraying water.
[0023] Subsequently, said condensate water advances, to said third tank, where said compressor chiller further refines (lowers) said condensate water’ s temperature. This ensures that said condensate water that is supplied, to said fresh air supply fan coil or said honeycomb filter, is chilled. A plurality of pumps facilitates pumping of said condensate water.
[0024] Water level sensors may be disposed in (or may be disposed within) said collection tank, said tank, and said third tank. Said water level sensors sense water levels, in said collection tank, said tank, and said third tank, in real-time, with sensed data being transmitted, to said controlling member. Based on said sensed water levels, and comparison, with a water level threshold value (or respective water level threshold values), said controlling member transmits instructions, to allow circulation or draining of water. Said water level sensors also prevent overflow and burnouts.
[0025] The disclosed apparatus offers at least the following advantages: is simple in construction; is cost-effective (costs about Rs. 25,000); is configured to be retrofittable; and / or is suitable, for various indoor environments, including but not limited to: domestic environments; cottage- scale environments; micro- scale environments; small-scale environments; medium-scale environments; and / or the like. Unlike traditional systems that rely solely on said air conditioner's cut-off mechanism, said apparatus prioritises air quality and temperature, at the approximate height of human breath.
[0026] By focusing on conditions, at human height, said apparatus dynamically addresses comfort needs of occupants directly. Said apparatus also addresses health and wellbeing needs of occupants, and helps, in relation to energy savings.

In addition, the order of the operations may be re-arranged. A method may be terminated, when its operations are completed, but may also have additional steps.
[0051] An apparatus, for ventilating an environment (also referred to as “apparatus”), is disclosed. In an embodiment of the present disclosure, as illustrated, in Figure 1, the apparatus broadly comprises: a controlling unit (100); a fresh air supply fan (201; may also be referred to as “fan system” and / or “fan”); a fresh air supply fan coil (300; for example, made of copper or aluminium; may also be referred to as “coil” and / or “fan coil unit”); and a reservoir system (400).
[0052] As illustrated, in Figure 5, the controlling unit (100) broadly comprises: an at least a carbon dioxide sensor or oxygen sensor (101); a sampling fan (102); an at least a temperature sensor (103); and an at least a humidity sensor (104).
[0053] The controlling unit (100) may also comprise: an at least an indoor air quality sensor (106); and an at least a volatile organic compounds sensor (107). The at least one carbon dioxide sensor or oxygen sensor (101), the at least one temperature sensor (103), the at least one humidity sensor (104), the at least one indoor air quality sensor (106), and the at least one volatile organic compounds sensor (107) may be of any suitable type known in the art.
[0054] A controlling member (108; for example, a microcontroller; may also be referred to as “CPU”) is communicatively associated with at least: the at least one carbon dioxide sensor or oxygen sensor (101; for example, based on non-dispersive infrared technology); the at least one temperature sensor (103); and the at least one humidity sensor (104).
[0055] The controlling member (108; for example, a microcontroller) may also be communicatively associated with the at least one indoor air quality sensor (106) and the at least one volatile organic compounds sensor (107). The controlling member (108) is configured to monitor and control operations of the apparatus. The at least one carbon dioxide sensor or oxygen sensor (101) senses carbon dioxide levels or oxygen levels of an environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0056] The sampling fan (102) draws in surrounding air, and directs it, towards the at least one carbon dioxide sensor or oxygen sensor (101). Once the air is sampled, the sampling fan (102) also exhausts the air, ensuring a constant flow of fresh samples.
[0057] The at least one temperature sensor (103) senses a temperature of the environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0058] The at least one humidity sensor (104) senses a humidity of the environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0059] The at least one indoor air quality sensor (106) senses indoor air quality levels of the environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0060] The at least one volatile organic compounds sensor (107) senses volatile organic compounds levels of the environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0061] In another embodiment of the present disclosure, the apparatus comprises a display. The sensed data that is (or are) transmitted, to the controlling member (108), is (or are) displayed, through the display.
[0062] An example of how to interpret displayed values is as follows:
[0063] Based on the sensed data, and based on comparisons of the sensed data, with an at least a threshold value or an at least a threshold range (or respective threshold values, or respective threshold ranges), the controlling member (108) transmits instructions (signals), to the apparatus, for operating the apparatus.
[0064] The controlling member (108) is also communicatively associated with an air conditioner and a ceiling fan, through an at least an infrared sensor. Alternatively, the controlling member (108) is also communicatively associated with only the air conditioner, through the at least one infrared sensor.
[0065] Through the at least one infrared sensor, the controlling member (108) switches on (and switches off) the air conditioner and the ceiling fan, based on the sensed temperature values. Through the at least one infrared sensor, the controlling member (108) may also control the air conditioner’s temperature.
[0066] For example, the air conditioner is switched off, and the ceiling fan is switched on, when the temperature of the environment is determined as being about 23 degrees Centigrade. Likewise, the ceiling fan is switched off, and the air conditioner is switched on, when the temperature of the environment is determined as being about 28 degrees Centigrade.
[0067] Alternatively, the air conditioner is switched off, and the ceiling fan is switched on, or the air conditioner’s temperature is regulated, as follows (time may be determined, by the apparatus, through a real-time clock):
[0068] As illustrated, in Figure 7, a person skilled in the art will appreciate the fact that apparatus may also comprise relay switches, to ensure precise and timely activation or deactivation, in response to sensed data or user inputs.
[0069] The fresh air supply fan (201) broadly comprises: a filtration member (202); and a honeycomb filter (203). The fresh air supply fan (201) may also comprise an atomiser (204).
[0070] The fresh air supply fan (201) may be a DC (Direct Current) fan that comprises a Variable Speed Drive (VSD) or a Variable Frequency Drive (VFD). The fresh air supply fan (201) may be configured with adjustable speed settings or may be configured with a constant speed setting.
[0071] When the carbon dioxide levels or oxygen levels are determined as being above a threshold value (for example, carbon dioxide levels above about 800 ppm, or carbon dioxide levels that do not fall within a range of between about 600 ppm and about 800 ppm, or oxygen levels below about 19.5%, or oxygen levels that do not fall within a range of between about 19.5% and about 20.5%), the fresh air supply fan (201) is switched on, by the controlling member (108), to enhance air circulation and promote intake of fresh air. Alternatively, when the carbon dioxide levels or oxygen levels are determined as being below the threshold value, the fresh air supply fan (201) is switched off, by the controlling member (108), to promote energy savings.
[0072] In yet another embodiment of the disclosure, the controlling member (108) is configured to be self-learning; it utilises information gathered, from previously received data, to improve its performance and efficiency.
[0073] An extensive (or full-fledged knowledge base) is stored, on the cloud, with a refined version of the knowledge base (or a fine-tuned version of the knowledge base, or a minimalistic version of the knowledge base, or a compressed version of the knowledge base, or a pruned version of the knowledge base) being stored, on the controlling member (108).
[0074] The knowledge base, on the cloud, syncs at regular, periodic intervals, with the controlling member (108), and is configured to learn and improve itself, based on the data received continuously, from the controlling member (108).
[0075] For example, if historical data indicates that certain environments are frequently occupied, during specific times: based on instructions that are transmitted, by the controlling member (108), the fresh air supply fan (201) pre-emptively starts, ensuring a fresh and comfortable environment, even before occupants arrive.
[0076] This historical data may also be used, to estimate reductions, in the fresh air supply rates, thereby, prompting or alerting the user, to clean the filtration member (202), to ensure steady supply, and avoid energy losses associated with a clogged filter.
[0077] As illustrated, in Figure 6, the apparatus also comprises a tilted tube or pipe, to capture ambient air. The tube is intentionally slanted, to allow for air purification. As the ambient air is drawn, it encounters the atomiser (204) that is disposed before the filtration member (202). This serves a dual purpose: firstly, it acts as a gentle mist that dampens the incoming air; and, secondly, it serves as a filtration system. The mist created, by the atomiser (204), is laden, with tiny water droplets.
[0078] As the air moves, through the tilted tube, dust particles and impurities present are suppressed and washed away. This is especially useful, for cities, where the ambient air has significant amounts of particulate matter. At the bottom of the tilted tube, a drain removes the collected water and particles.
[0079] The filtration member (202) captures dust particles, pollen, mould spores, allergens, and other impurities that are present (in the incoming fresh air). The filtration member (202) is replaceable or washable.
[0080] For cooling efficiency, especially in humid areas, the apparatus comprises: the reservoir system (400); and the fresh air supply fan coil (300) (with a pump-based circulation mechanism). The reservoir system (400) may be communicatively associated with the controlling member (108) and comprises a plurality of pumps (404). The reservoir system
[0081] (400) may be disposed within the environment or outside the environment.
[0082] As illustrated, in Figure 4, the reservoir system (400) broadly comprises: a collection tank
[0083] (401); a tank (402) that houses a cooling tower (405); and a third tank (403) that houses a compressor chiller (408) and its (compressor chiller’s) copper coil (410). The reservoir’s configuration provides an additional degree of condensate water cooling, prior to its distribution, to the fresh air supply fan (201). A person skilled in the art will appreciate the fact that, in high humidity level regions, the cooling tower (405) may prove to be less effective, due to the already saturated air.
[0084] In low humidity or dry environments, where not enough condensate water may be produced, for the collection tank (401), the collection tank (401) may also have a direct plumbing connection, for tap water (411). For an about 2 tonne air conditioner, the volume of the reservoir system (400) is about (30 cm * 30 cm * 30 cm) * 3.
[0085] Initially, in the collection tank (401), the condensate water is collected; it is then directed, to the tank (402). Within this tank (402), the condensate water undergoes a process of additional cooling, through induced evaporation. This tank (402) comprises an aerator (406). Said tank (402) also comprises an additional pump (407), for spraying water.
[0086] Subsequently, the condensate water advances, to said third tank (403), where the compressor chiller (408) further refines (lowers) the condensate water’ s temperature. This ensures that the condensate water that is supplied, to the fresh air supply fan coil (300) or said honeycomb filter (203), is chilled.
[0087] For example, in a scenario where external temperatures soar to about 35 degrees Centigrade, with humidity levels reaching about 80%, for the air conditioner's setpoint of about 24 degrees Centigrade, the temperature of the condensate water is likely to be between about 14 degrees Centigrade and about 16 degrees Centigrade.
[0088] As the condensate water is initially collected, in the collection tank (401), its temperature may be about 16 degrees Centigrade. Upon reaching the tank (402), the condensate water’s temperature may be about 13 degrees Centigrade. In the third tank (403), the condensate water’s temperature may be reduced, to about 7 degrees Centigrade. Water level sensors (409) may be disposed in (or may be disposed within) the collection tank (401), the tank (402), and the third tank (403). Said water level sensors (409) sense water levels, in the collection tank (401), the tank (402), and the third tank (403), in realtime, with sensed data being transmitted, to the controlling member (108). Based on the sensed water levels, and comparison, with a water level threshold value (or respective water level threshold values), the controlling member (108) transmits instructions, to allow circulation or draining of water. The water level sensors (409) also prevent overflow and burnouts.
[0089] Return water, from the fresh air supply fan coil (300), takes one of the following routes: a) To the collection tank (401), in case the water level, in the collection tank (401), is less than twice the height of a pump (disposed inside the collection tank (401)), among the plurality of pumps (404); or b) To drain, if the water level, in the collection tank (401), is greater than twice the height of the pump (disposed inside the collection tank (401)), among the plurality of pumps (404).
[0090] In yet another embodiment of the disclosure, a three-way valve safeguards operational efficiency of the apparatus. When there is a minimal temperature difference (for example, as sensed, by a plurality of temperature sensors, which are communicatively associated with the controlling member (108)), between the fresh air supply fan coil’s (300) return water and the condensate water, the controlling member (108) transmits instructions, to the three-way valve, to allow for combining of the fresh air supply fan coil’s (300) return water and the condensate water.
[0091] One temperature sensor, among the plurality of temperature sensors, senses a temperature of the fresh air supply fan coil’s (300) return water, in real-time, with sensed data being transmitted, to the controlling member (108).
[0092] Another temperature sensor, among the plurality of temperature sensors, senses a temperature of the condensate water, in real-time, with sensed data being transmitted, to the controlling member (108). In yet another embodiment of the disclosure, for hot and dry conditions, if the controlling member (108) determines that the humidity is below about 45% (a predefined threshold value), based on the data that is (or are) sensed, by the at least one humidity sensor (104), the controlling member (108) transmits instructions, to the three-way valve, to allow the return water, to pass, through the honeycomb filter (203), till the humidity is determined as being about 60% (a second predefined threshold value) i.e. till the humidity is determined as being between the predefined threshold value and the second predefined threshold value.
[0093] As illustrated, in Figure 3, in yet another embodiment of the disclosure, the apparatus is configured to be retrofittable, onto existing air conditioning or HVAC systems.
[0094] In yet another embodiment of the disclosure, the apparatus is configured, monitored, and controlled remotely, by the user, through an application on a computing device. The user interacts, with the apparatus, through a user interface (or display) of the computing device, which functions as an interface. Results of the analyses (or comparisons) performed, by the controlling member (108), are displayed, on (or through, or by) the user interface of the computing device.
[0095] Communicative association with the application on a computing device may occur, through wired or wireless technologies, such as: intranet; internet; mobile data; Bluetooth Low Energy; LoRa; ZigBee; and / or the like.
[0096] A person skilled in the art will appreciate the fact that the apparatus may be powered, by an at least a power source (109). The at least one power source (109) may be of any suitable type known in the art. For example, the at least one power source (109) is a rechargeable battery. A person skilled in the art will also appreciate the fact that the apparatus may be configured with wireless and wired connectivity options.
[0097] As illustrated, in Figure 2, in sitting environments (where individuals are normally seated), the apparatus is installed (or is disposed), at a height that ranges between about 1.5 feet and about 4.5 feet (from a floor), depending on heights of the individuals.
[0098] In sleeping environments (for example, bedrooms), the height, at which, the apparatus is installed (or is disposed), depends on the height of a bed. For environments of upto about 2,000 square feet, one apparatus, for example, disposed on (or mounted on, or installed on, or associated with) a farthest corner (of the environment) may be sufficient.
[0099] An example of the apparatus’s method of operation is as follows:
[0100] Once the apparatus is switched on, the sampling fan (102) draws in the surrounding air, and directs it, towards the at least one carbon dioxide sensor or oxygen sensor (101). The at least one carbon dioxide sensor or oxygen sensor (101) senses the carbon dioxide levels or oxygen levels of the environment, where the apparatus is installed (or is disposed), in real-time, with sensed data being transmitted, to the controlling member (108).
[0101] If the controlling member (108) determines a ventilation need, based on the sensed carbon dioxide or oxygen levels, it transmits instructions, causing switching on of the fresh air supply fan (201). If the controlling member (108) determines that the humidity, as sensed, by the at least one humidity sensor (104), is less than about 45% (the predefined threshold value), the controlling member (108) transmits instructions, to the three-way valve, to allow the AC condensate water or tap water, to pass, through the honeycomb filter (203), till the humidity is determined as being about 60% (the second predefined threshold value).
[0102] After the humidity is determined as being about 60% (the second predefined threshold value), the controlling member (108) transmits instructions (to the three-way valve), to allow passing of the AC condensate water or tap water, through the fresh air supply fan coil (300).
[0103] The apparatus was tested, under a non-disclosure agreement, in a facility of about 1,500 square feet, with dynamic occupant load, throughout the day. As illustrated, in Figure 8, with the apparatus, peak carbon dioxide levels were diluted, to acceptable levels, within about 47 minutes.
[0104] Figure 9 illustrates another embodiment of the apparatus (for all types of weather conditions). In this embodiment, in addition to the compressor chiller (408), the reservoir system (400) (or the third tank (403)) also comprises a heater or a geyser (412). External temperature is sensed, by an at least an external temperature sensor, or through an API link. The at least one external temperature sensor is communicatively associated with the controlling member (108).
[0105] If the controlling member (108) determines that the external temperature is below about 15 degrees Centigrade, the controlling member (108) transmits instructions, to redirect the return water, directly to the third tank (403), while also initiating the heater (412). Depending on requirements, the user actuates the compressor chiller (408) or the heater (412), through the application on a computing device and the controlling member (108). Alternatively, or in addition, the requirements may be deciphered, by the apparatus, through the at least one external temperature sensor.
[0106] If the controlling member (108) determines that the external temperature is below the internal temperature, the controlling member (108) transmits instructions, to supply the fresh air, directly to the environment (for example, a room), to free cool the environment. The controlling member (108) may switch the air conditioner off, and supply fresh air, at a lower temperature, to promote energy savings.
